An astronomical telescope is able to resolve two stars at an angular separation of

10^{-3}

degree. If wavelength of light used is

500 {~nm}

, then the diameter of the objective of the telescope is

View answer and explanation

Correct option: A

3.5 {~cm}

Option A (

3.5 {~cm}

) is correct because it is calculated using the formula for the limit of resolution of a telescope, considering the given wavelength and angular separation.
